For all you Series I Mazda RX-8 owners, we are proud to announce VersaTuner support for Series I RX-8s.

We received so many requests for Series I RX-8 support over the years that we decided to sort through the alphabet soup of ECU calibrations and add support for Series I RX-8s. We leveraged our experience race tuning SCCA Series II RX-8s and did extensive beta testing on multiple years and market regions. We think you will be very happy with the results.
